Cant parse all elements of XML to C#?

Hello everybody, Im a total noob in this. I tried to parse a Xml to C#.So I managed it somehow, now I stock.I will need all of the content of the elements of the XML but my C# code can only read to "mouth4":

 <visimes>
      <text>hello world</text>
     <voice>usenglishfemale</voice>
     <length>753</length>
     <frames>9</frames>
     <visime>
       <start>1</start>
       <end>74</end>
       <index>1</index>
       <length>74</length>
       <mouth>12</mouth>
     </visime>
     <visime>
       <start>75</start>
       <end>102</end>
       <index>2</index>
       <length>28</length>
       <mouth>4</mouth> //----------------This is the last output----------------
    </visime>
     <viseme>
       <start>103</start>
       <end>182</end>
       <index>3</index>
       <length>80</length>
       <mouth>14</mouth>
    </viseme>
    <viseme>
       <start>183</start>
       <end>269</end>
       <index>4</index>
       <length>87</length>
       <mouth>8</mouth>
    </viseme>
    <viseme>
       <start>270</start>
       <end>359</end>
       <index>5</index>
       <length>90</length>
       <mouth>7</mouth>
    </viseme>
    <viseme>
       <start>360</start>
       <end>470</end>
       <index>6</index>
       <length>111</length>
       <mouth>5</mouth>
    </viseme>
    <viseme>
       <start>471</start>
       <end>660</end>
       <index>7</index>
       <length>190</length>
       <mouth>14</mouth>
    </viseme>
    <viseme>
       <start>661</start>
       <end>752</end>
       <index>8</index>
       <length>92</length>
       <mouth>19</mouth>
    </viseme>
    <viseme>
       <start>753</start>
       <end>753</end>
       <index>9</index>
       <length>1</length>
       <mouth>0</mouth>
    </viseme>
 </visimes>

   

of the xml. Any idea what I miss here?I want to get all elements of "visime" after a little delay of time. Here is my C# code:

     void Start()
         {    
             StartCoroutine(GetVisimes());
     
             wait_framerate =0;//Start at 0
         }
     
         IEnumerator GetVisimes()
         {
     
                 XmlDocument xmlDoc = new XmlDocument(); document.
             xmlDoc.LoadXml(GameAsset.text);
     
             XmlNodeList visimesList = xmlDoc.GetElementsByTagName("visimes"); 
 
 foreach (XmlNode visimeInfo in visimesList)
             {
                 XmlNodeList visimeContent = visimeInfo.ChildNodes;
                 
     
         
                 foreach (XmlNode visimesItens in visimeContent) // levels itens nodes.
                 {
     
                     if(visimesItens.Name == "text")
                     {
                         
                         Debug.Log (visimesItens.InnerText);
                         Text=visimesItens.InnerText;
     
             
                     }
                     if(visimesItens.Name == "voice")
                     {
                         
                         Debug.Log (visimesItens.InnerText);
                         Voice=visimesItens.InnerText;
                     }
                     if(visimesItens.Name == "frames")
                     {
                         
                         Debug.Log( "frames=" + visimesItens.InnerText);
                     
                         Frames= int.Parse (visimesItens.InnerText);
                     }
                     if(visimesItens.Name == "length")
                     {
